Abstract: In an electronic control unit, a traveling mode switching control unit switches a traveling mode from an N mode to a B mode when a shift lever is operated to a B operation position while the traveling mode is the N mode and the vehicle is traveling forward.

Accordingly, it is possible to prevent a driver from experiencing difficulty in operating the shift lever at the time of switching the traveling mode from the N mode to the B mode during forward coast traveling in the N mode.
